escaping

I have a problem writing my XSL. I have a link with the following code: <a> <xsl:attribute name="href"> <xsl:value-of select="concat($myUrl,'&projectNumber=',$projectNumber)"/> </xsl:attribute> <xsl:attribute name="title"> <xsl:value-of select="title"/> </xsl:attribute> LINK </a> So I need to pass a variable projectNumber to the end of myUrl . This works just fine and I get ...myUrl...&projectNumber=...projectNumber... in HTML. The problem is, that the variable projectNumber sometimes has some characters which have to be escaped in the href of my link. I tried using the XSL function str:escape

I have the following text $text = "\\vct=140\\Araignée du soir espoir,araignée du matin,espoir du matin." I want to remove the escape characters using php..I do not want to use stripslashes since it is server dependent.. I want to remove the '\' before the '\vct=140' and the '\' before '\Arai....' How can I remove them from the string? As far as I can tell stripslashes works as per the manual : <?php $string = '\\\\vct=140\\\\Araignée du soir espoir.'; echo $string, "\n"; echo stripslashes($string), "\n"; Which outputs: \\vct=140\\Araignée du soir espoir. \vct=140\Araignée du soir espoir.

I am learning how to use simplejson to decode JSON file. But I suffered the "invalid \escape" error. Here is the code import simplejson as json def main(): json.loads(r'{"test":"\x27"}') if __name__ == '__main__': main() And here is the error message Traceback (most recent call last): File "hello_world.py", line 7, in <module> main() File "hello_world.py", line 4, in main json.loads(r'{"test":"\x27"}') File "C:\Users\zhangkai\python\simplejson\__init__.py", line 307, in loads return _default_decoder.decode(s) File "C:\Users\zhangkai\python\simplejson\decoder.py", line 335, in decode obj, end =

The Java language specification states that the escapes inside strings are the "normal" C ones like \n and \t , but they also specify octal escapes from \0 to \377 . Specifically, the JLS states: OctalEscape: \ OctalDigit \ OctalDigit OctalDigit \ ZeroToThree OctalDigit OctalDigit OctalDigit: one of 0 1 2 3 4 5 6 7 ZeroToThree: one of 0 1 2 3 meaning that something like \4715 is illegal, despite it being within the range of a Java character (since Java characters are not bytes). Why does Java have this arbitrary restriction? How are you meant to specify octal codes for characters beyond 255?
